The explosion startled the surrounding craftsmen, and the ten craftsmen fell to the ground one by one, fearing that they would be injured by the explosion flames.
The explosion raised the temperature of the compound in the open cup, and highly toxic gases emerged.
Fortunately, the amount of mercury fulminate in the open cup was limited, and the air wave of the explosion was not large. It only scattered glass fragments more than one meter away. Even the craftsman who performed the reaction was not injured.
Those poisonous gases did not spread in the laboratory. There was an exhaust fan driven by a steam engine installed above the laboratory wall, which continuously pumped the air in the laboratory out of the laboratory and discharged it. Therefore, the poisonous gas only stayed in the laboratory for a few seconds.
It was taken outside by the exhaust fan.
Although it exploded, no one was injured.
Li Zhi smiled bitterly, secretly thinking that the technology of this base fire was not easy to master.
In fact, Li Zhi estimated that the preparation of this thing should not be complicated. After all, mercury fulminate had been produced by Kunkel in the late 16th and early 17th centuries. By the 21st year of Chongzhen, the preparation of mercury fulminate in the West had been basically mature, which shows the technical difficulty.
Not big.
However, there are obviously some tricks to the preparation of this compound. Li Zhi also wanted to know some methods of preparing mercury fulminate before traveling through time, but the relevant information was strictly controlled by the government and was not allowed to be consulted by civilians at all. So even if Li Zhi is
An experienced industrial designer does not understand the specific process.
It was unrealistic to learn specific processes from Westerners. At this time, mercury fulminate had not yet been used in firearm primers, and the production process was only in the hands of a few naturalists. Li Zhi had no idea where to look for these naturalists.
It is estimated that it will take several years to go to Europe to search.
So I can only explore it myself.
Although they had been prepared to take risks, the feeling was different when they actually faced danger. The ten craftsmen were frightened by the exploding glass, and their faces were a little horrified, and they looked at it in panic.
Li Zhi.
Li Zhi said: "Okay, everyone has seen that mercury fulminate is unstable. This substance is especially prone to explosion when heated, so everyone should be careful when handling it."
"In the future, you are not allowed to use your hands to operate the glass during testing. All operations must be done from a distance using tweezers. During testing, you must also operate under an exhaust fan to avoid inhaling toxic gases."
"However, experiments must continue. Everyone uses their brains to study why mercury fulminate explodes during the preparation process, and test safe preparation methods."
"If the research is finally completed, everyone will be rewarded fifty taels of silver."
Everyone's eyes lit up when they heard the bonus figure of fifty taels of silver. This figure was enough to buy half of a small villa in Fanjiazhuang. This income was enough for the craftsmen to take some risks. They became excited again and began to clean up the broken glass on the floor.
, prepare for the next test.
Seeing that the craftsmen were all full of energy, Li Zhi nodded and left the laboratory.

On the first day of March, Li Zhi directed the construction workers to start building the tap water system in the palace, which was the original Duke's palace.
Li Zhi wants to build the first tap water system of this era.
For Daming, who relies on buckets for water, tap water is really convenient. When Li Zhi traveled through the first few months, the most unaccustomed thing was the lack of tap water. He could endure without electricity, but he couldn't tolerate without tap water. Wash your hands.
You have to go to the water tank in the yard to scoop water. To take a bath, you have to carry a few buckets of water to the bathroom.
Even now, the people of Fanjiazhuang have several large water tanks in their villas, one in the kitchen, one in the sink, and one in the yard next to the sewer, taking up a lot of space in their homes.
Even though Li Zhi invented the flush toilet, which improved the hygiene level of the people in the territory, the flush toilet still relied on the user to carry a bucket to fill the pool, which was very inconvenient.
There is an urgent need to introduce a tap water system.
The old-fashioned tap water systems of later generations used galvanized pipes. As an industrial designer, Li Zhi knew that the galvanized layer of this kind of water pipe was actually a decoration. After ten years of use, the galvanized layer inside the steel pipe will definitely fall off.
.In those houses that are more than 20 years old, once the water pipes are cut, they are full of rust.
If the faucet has not been used for a long time, you will find that the tap water is yellow after unscrewing it. This is because rust is dissolved in the tap water.
But in fact, these rusts are harmless. For tap water pipes that have been used frequently for a long time, the rust in the tap water per unit is very small, and it is not at a level that is harmful to health. Therefore, even if the tap water pipes in later generations of houses are severely rusted
, and it never said that new water pipes must be replaced.
In fact, tap water contains a small amount of ferric oxide, which can also supplement iron.
If the water pipe has not been used for a long time, drain the yellowed rusty water the first time it is used, and the remaining water will still be drinkable.
Li Zhi cannot produce galvanized pipes now, but since rust will not affect the quality of drinking water, Li Zhi just uses ordinary iron pipes as tap water pipes.
The joints of tap water pipes will leak, and later generations used raw tape to seal them. There was no raw tape in this era, but Li Zhi used natural resin for sealing, and the effect was equally good. The tap water faucet does not require high accuracy. Li Zhi's current machine tool factory
Can be mass produced.
According to Li Zhi's design, the construction workers dug a large well in the palace and drove a dragon tail car diagonally into the well. After the dragon tail car raised the well water to a pool on the ground,
Another dragon tail car is set up in this pool to lift the water to the fifteen-meter-high water tower.
Water pipes are installed on the water tower, and the water pipes are buried under the ground, introducing water from high places to various water uses in the palace. Faucets are installed next to the kitchen, toilet, bathroom and sink.
It took a long time to install the water pipes in the entire palace, and no one was installed properly. But the main courtyard of the harem where Li Zhi and Cui lived together took only one day to install the water pipes. After a little adjustment, Li Zhi was happy to use it.
Tap water.
When the tap was turned on, Cui He was startled by the gush of tap water.
Cui He was already six months pregnant at this time, and her belly was very swollen. However, she was still attracted by the gurgling water from the sink and stood beside the sink and stared at it for a long time.
"Your Majesty, where does this water come from? Why does it look like a mountain spring?"
Li Zhi tightened the faucet, turned off the tap water, then turned on the water again, and said with a smile: "This is not a mountain spring, this is tap water. This water is pressed from the water tower outside. In the future, with this water, we can always
Got convenient water supply in the room.”
Cui He stood by the pool and looked at it for a long time, and suddenly said: "This must be using the physical siphon principle!"
Cui He had nothing to do at home. He asked Li Zhi to read the physics and chemistry textbooks in the polytechnic, and he immediately guessed the principle of the tap water system.
Li Zhi was stunned for a moment, pinched Cui He's cheek and said, "The princess is really smart!"
